LOCKINGDEVICEV SPECIFICATION forming part of Letters Patent N 0. 608,185 dated August 2, 1898. Application filed June 16, 1896. Serial No. 595,813. (1% model.)

To all whom, it may concern:

Be it known that I, JOHN E. DOLDT, oft-he city and county of Providence, State of Rhode Island, have invented certain new and useful Improvements in Looking Devices; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming part of the same, to be a full, clear, and exact description thereof.

The object of the present invention is to provide a device whereby a bicycle or any other article may be securely locked in the place where it is left upon the payment of a predetermined fee and without the assistance of an attendant.

To this end one feature of invention comprises a means for engaging and securing the bicycle or other article in place and a device for looking said securing device, which is normally inoperative, but may be moved into operative position upon the insertion of a coin of predetermined value in the proper place.

Another feature of invention relates to" means for preventing the removal of the key from a key-controlled locking device until a coin of the proper denomination is inserted. Each of these features of invention may be embodied in structures in which the other feature is not present, if desired; but the preferred form of locking device embodies both of these features as well as other features of invention which will be set forth in the claims. In the accompanying drawings, which show a locking device embodying the various features of invention in their preferred forms, the securing device is mounted in asuitable support, which is also provided with a slot or opening for the reception of a coin. Also mounted within the support are means for locking the securing device in position, which means are normally inoperative. The locking means is provided with a keyor key-blank which is normally retained in such a position that it is non-removable or inaccessible.

The mechanism shown also comprises two movable parts, one of which is accessible from the outside of the support or is connected with a part which is so accessibleas, for instance, with the key or the securing-barsaid latter part being capable of movement independent of the other part. Vhen a coin is inserted in the slot in the support, it enters a coin-receiver so constructed and arranged that the insertion of the coin serves to connect the two movable parts, so that by moving the accessible part the lockin g device is operated and the key released or delivered.

Referring to the drawings, Figure 1 is an elevation of a locking device mounted in a post and especially adapted for the securing of bicycles, showing a bicycle in place. Fig. 2 is a front elevation of the locking device, showing the securing device unlocked. Fig. 3 is a similar view showing the securing device locked. Fig. 4 is a rear elevation, with the parts in the position shown in Fig. 2. Figs. 5 and 6 are elevations, with the rear disk removed. Fig. 7 is a vertical transverse sectional view. Fig. 8 is an elevation of a modification.

A represents a post in which the locking device is mounted and which may be located in any locality where bicycles are ordinarily left,

as along the sides of streets, at clubs, steamboats, race-tracks, 65C. The lockingdevicein the form shown consists of the securing, hasp orbarl, which is of a form to engage the head of the bicycle and support the same and is adapted to be locked in position by coin-controlled means. The postA is provided with a slot B, in which the coin may be inserted, said coin dropping into a suitable receptacle 0 as the locking means is operated, as will be more fully described hereinafter. A door D is provided through which the receptacle 0 may be removed, said door being provided with a padlock or other lock. Any suitable coin-controlled means may be employed for locking the securing hasp or bar in position to secure the bicycle, and the preferred form shown in the drawings will now be described.

A plate 2 is secured within the post A and serves as a support for the parts to'be described. A bracket 4: depends from the plate 2 and has formed therein a bearing 5, in which the securing-bar 1 slides. A collart is secured to said bar 1, and a coiled spring 7 is interposed betweensaid collar and the side of the post A and serves to hold said bar in position. The bar 1 is provided with a notch 8, which is in position to be engaged by an engaging device in the form of a pin or bolt 9, sliding in a boss 10, projecting from the bearing 5 and operated as hereinafter described. Secured to the bracket 4 and eX- tending outside the post A is an ordinary lock 1la Yale or Corbin lock, for instancewhich is provided with bar 12, which is revolved whenever the key 13 is turned. The bracket 4 is provided with a bearing 14, in which is mounted the hub 15 of a disk 16, said hub being secured to the bar 12, so that the turning of the key 13 also turns the disk 16. A pin orlug 17 projects from the face of disk 16 and engages either end of a lever 18, loosely pivoted 011 the hub 15 between the disk 16 and the bearing 14 and rocks said lever in one direction or the other, according as the disk 16 is turned in one direction or the other by the key 13. The lever 18 is connected with the pi n or-bolt 9 and serves to move said pin to lock or unlock the bar 1. Rotation of the disk 16 to effect the locking of the bar 1 is prevented by means of a spring-stop 20, which is mounted to slide in a bracket 19, which stop projects into a recess 21, formed in the disk 16. The recess 21 is provided with the two radial shoulders 22 and 23, and said shoulders limit the movement of the disk 16 by engaging the stop 20. WVhen the recess 21 is engaged by the stop 20, the key 13 is in such a position that it cannot be removed from the lock, and the stop thus serves as a means for preventing the removal of the key, since it is necessary to turn the key into the position shown in Fig. 3 in order to remove the same.

In order to render the locking means operative and also to deliver the key on the insertion of a coin of the proper denomination, the following means are provided:

The disk 16 is provided on its rear face with a hub 24, on which is loosely mounted an annular ring 25. A recess 26 is formed in the ring and is provided with the radial shoulder 260 and the cam-surface 27, and said recess is engaged by the stop 20. A slot 28 is formed in the face of hub 24 and is arranged to register with two slots 29 30, formedin the annular ring 25, when the stop 20 is in engagement with the shoulders 22 and 260, as shown in Fig. 5. The slots 29 30 are formed of a size to admit a coin of a certain denomination-as, for instance, a nickel-but the slot 28 is contracted at its upper end, so that the coin will not pass therethrou gh,al thou gh coin s of a smaller size may pass through. It will thus be seen that the slot 29 and the recess in the hub 24, formed by the reduced end of the slot 28, form a two-part coin-receiver, one part of which is connected with the disk 16 and the other part with the cam 27; A disk 31, provided with a hub 32, mounted in a bearing 33, covers the face of hub 24 and ring 25 and serves to retain the coin in the slots formed therein, and said disk is preferably secured to the hub 24 and revolves therewith and is provided with a recess 34, corresponding to recess 21 in disk 16. The disks 16 and 31 and the ring 25 are each provided with registering recesses 35, which are engaged by the stop 20 when said parts have been revolved into the position shown in Fig 3. Each of these recesses is provided with the radial shoulder 37 and the cam-surface 38, and the stop 20 acts against the cam-surfaces to hold the shoulders 37 in line, and thus hold the parts in the position shown in Fig. 3, in which position the key 13 may be removed from or inserted in the lock 11. A pin, preferably pin 17, projects from disk 16 through a slot 36 in the ring 25, said slot being long enough to allow the disk 16 to be turned to bring the shoulder 23 against the stop 20 without affecting the ring 25.

r The operation is as follows: The parts normally stand in the position shown in Figs. 1, 2, 4, and 5, with the key 13 in such a position that its removal from the lock 11 is prevented and with the bolt 9 withdrawn, so that the securing device 1 is not locked in position. With the parts in this position it is impossible to turn the disk 16 to operate the bolt 0 because of the shoulder 23 and stop 20. When it is desired to secure a bicycle to the post A, the bar 1 is drawn out against the tension of the spring 7 and the bicycle-head inserted in the hook on the end of said rod, the spring serving to return the bar to its normal position, as shown in Figs. 1 and 2. A coin is then inserted in the slot B and passes down through a slot formed in the plate 2 and into slot 29, being arrested by the contraction in the slot 28, as shown in dotted lines in Fig. 5. The coin now serves to connect the disk 16 and ring 25, and if the key 13 is turned in .the direction of the arrow, Fig. 2, the ring and disk 16 are revolved, the cam-surface 27 forcing back the stop 20 out of the path of shoulder 23. As the key is turned into the position shown in Fig. 3 the pin 17 engages the lever 18 and slides the bolt 9 into the re cess 8, thus locking the bar 1 in position. As the parts reach this position the stop 20 enters the notches or recesses 35, and by its action against the cam-surfaces 38 brings the shoulders 37 against said stop, and thus holds the slots 28 and 29 in alinement and relieves any cramping effect which the side of said slots may have upon the coin, which said coin is now free to drop out of said slots and into the receptacle 0. A guard 41 prevents the accidental escape of the coin before the parts reach the position shown in Figs. 3 and 6. The key 13 may now be removed and be retained by the owner of the bicycle. Then he desires to remove his wheel, he inserts the key in the lock 11 and turns said key in the direction of the arrows, Figs. 3 and 6. The pin 17 now engages the end of slot 36 and causes the disk 16 and ring 25 to be turned in unison, and the cam-surface 38 acts to force back the stop 20 out of recesses 35, and the parts are returned to the position shown in Figs. 2, 4, and 5, the pin 17 striking the opposite end of the lever 18 and operating the bolt 9 to unlock the bar 1. The lever 18 may be retained in position until engaged by the pin 17 by thefriction of the parts; but it is preferred to use a spring-catch 39, which engages notches in said lever and holds said lever in either of its positions.

By forming the recess 21 on the opposite side of the disk 16 and forming the slot 36 on the other side of pin 17 the coin-controlled locking means will be so changed that the inand there is no slot-and-pin connection becam-surface 38.

tween the disk 16 and ring 25. The recesses 35 in the disks 1G and 31 are also provided with a second radial shoulder 12 instead of the In other respects the parts are as above described. The action in lock ing the bar 1 in position is the same as above described. NVhen it is desired to unlock the bar 1, however, the presence of a coin in the slot 30 is necessary to connect the disk 16 and ring 25, so that they may turn in unison, and the cam-surface 38 on said ring may force the stop 20 back out of the path of shoulder 12.

Vhile a device has been shown and described which is particularly adapted for use in securing bicycles, it will be understood that the invention is not limited to such use, but may be used for securing other articles in place.

It is preferred to employ a locking means in which a projecting key is used to eitect the locking and unlocking of the securing device; but it will beundersto'od that such eonstruetion is not essential and that other means could be used for operating the looking means.
